WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2008 GMC Yukon XL, 2008 GMC Yukon, 2008 Chevrolet Tahoe, 2008 Chevrolet Suburban, and 2008 Cadillac Escalade EXT. However, it is still accessible from the selected car via links, so may be relevant.

With the stop lamp switch removed, use a DMM to measure resistance across the pins of the voltage circuit and the stop lamp switch signal circuit. With the stop lamp switch plunger released, the DMM resistance should display infinite resistance. With the stop lamp plunger depressed the stop lamp switch resistance should be less than 10 ohms.
